APPARATUS FOR GOVERNING THE ?ASSAG-E OF CARS OR VEHICLES ALONG A RAILWAY.

Patented July 7, 1908.

To all whom it may concern:

Be it known that I, Jon): D. 'lnrron, a citizen of the United States, residing at Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements Relating to Apparatus for Governing the iassage of Cars or Vehicles Along a Railway, of which the following is a specification.

My invention relates to apparatus for governing the passage of cars or vehicles along a railway.

My invention has special reference to apparatus intended for operating railway switc ies for which electricity is en'iploycd as the motive power, as well as for actuating indication mechanism usually employed in connection with such apparatus. The supply of current thereto is controlled by circuit controllers operated from levers comprised in what is generally known as an interlocking machine which is generally arranged within a cabin or tower located at a distance 1 from the switch operating apparatus. Each lever on these machines is usually provided with mechanism known in the art as indicating mechanism such mechanism being actuated to release its lever, whereby the lever is permitted to be moved to its final position,and to release,through whatis known as mechanical interlocking, similar levers which may control'othcr apparatus for operating signal devices or otherswitch rails. ing mechanism when so actuated indicates that the apparatus controlled from the circuit controller and lever has operated in response to a. movement of the circuit controller and lever.

I will describe an apparatus, comprising an electric motorfor moving the switch rail or rails, and also a control therefor, embodying m invention and i then point out the novel eatures thereof in claims. My inven tion may also be used in connection with apparatus for operating signal devices comprising an electric motor the sup ly of current to which is under the contro of a lever, .and the lever'p'rovided witli an indicating mechanism. The signal device and the switch rails so far as my invention is concerned are equivalent devices as each controls in its way the passage of cars or vehicles along a railwa The accompanying drawings show die- The indicat grammatically certain devices comprising an electric motor, a source of current supply for said motor, a circuit controller and lever for controlling the supply of current to said motor; an indicating mechanism for the lever comprising a latch, and electro-mag nctic means for operating said latch, said elcctro-magnetic means comprising a rotating part which, 'upon rotation operates the latch to release the circuit controller and lever, anda source of current supply for said electromagnetic means. The said drawings further show diagrammatically certain devices comprising an electric motor, a source of current supply for said motor, a circuit controller and lever for controlling the supply of ciirrent to said motor, an indicating mechanism for the lever comprising'a latch, said electro-magnetic means for op I crating said lat-ch,- said electro-magnetic means comprising a rotating part which, upon rotation, operates the latch to release the circuit controller and lever, and means for supplying said elcct-ro-magnctic means with an alternating current.

I have not deemed it necessary to illustrate the various adjuncts connected to, or forming part of, the interlocking machine but have simply shown a circuit controller and movements of the switch rail or rails, and have also confined myself to illustrating, dia grammatically, a mechanical switch and lock movement which is here shown as comprising a screw for moving it from one position to. the other, an electro-magnetic clutch and an ordinary motor for giving rotation to said screw, the latter being geared to and connected u with the motor through the medium of t 1e clectro-magnetic clutch. This is illustrated and described in my co-pending application filed April 18th, 1904, Serial N 0. 203,645. This switch movement is arbitrarily chosen solely for the purpose of illustrating and explaining the essential features of my invention.

An object of the present invention is the provision of means whereby a unidirectional current is made to produce an alternating current for efi'ecting the op'eration'of the indication mechanism, the latter being so constructed and arranged as to remain unaffected by a unidirectional current or by accidental impulses of current, which may flow through lever usually employed for controlling the v Lil I mature f which upen retcticn cpemesthe locking means I01" the lever.

The segmental extension 2 is receeee' and clue e' s of is fcrmehczildecs 3 1 1 the mg 8 etc i c l. ebuts, e T the n cvemen'l- 0f lever 1 in eithez? all are in the position shown in Fig. 4, it will be apparent that the lever may be moved to the left, which constitutes the preliminary movement in that ction, and when such preliminary nun int ot' the lever has been affected the parts will be in the position shown in Fig. l, (which may be termed the commencement of the normal movement). The prelimin movement operates a circuit contrcl' l which may be of any de sired construction so that current from a battery $10 or other suitable source of supply will flow through wire 72, primary coil 28, of a iI'RESlOl'ZllBl or other analogous device 26, wires 71, $5, contacts 29, 36, 31 (of the circult controller), wire 73, field coil 88, of the switch opeifliiig motor M, wire 75, contacts 50, 4S, (of a suitable form of circuit con troller C which is operated by the switch and lock movement), wire 77, magnet 61, wires 84%, 85, brush 44, electro-magnetic clutch so, brushes 1-5, 43, armature 40, of the switch. operating motor, thence through brush t wires 86, and 87, back to battery Sit). The current flowing in this circuit causes the armature 40 to rotate and through the electro-magnetic clutch 46, which is energi' d by said current, the switch rails are moved from their reverse position to their position. While such curnormm rent flows through the coils of the magnet'ol, it has no etlect whatever on the electromagnetic controller, of which said magnet 61, forms part, except to hold the contact 58, (also forming a part of the electro-magnetic controller,) in the position shown.

The current just described being unidirectional and practically of uniform strength while it passes through the rimary coil 28 of the transformer 26, it will have no appreciable effect upon the secondary coil 27, so that the electrommgnetic controlling apparatus of the indicating mechanism cannot be energized to produce rotation.

"When the switch and lock movement has operated to move the switch rails to full normal pos' on as shown in Fig. 2, the circuit just described will be broken and s new circuit established, by reason of the sh. ting of the contact 48 of circuit controller ll trom the contact onto the contact 53.

in the new circuit established, current will flow fr 111 the battery 90 through wire 72, primary coil 28, wires '71, 65, contacts 29, 3G, 31,;wiro 73, field coil 38 of switch operating motor M, along wire 75, contacts 50, 48 and wire 78, contacts 57, 5S and 56, wires S1; 83, brush e2, thence through a collector ri' to described, through the motor or rture -20, brush fl], (or directly to the brush 4-1 itself) and wires 86, 87, baclr to batteryfitl. It will be observed that the clutch coil is not includedin this last named circuit. Therefore, the clutch is not energized and the motor runs free.

The brush 42,is adjusted with relation to What I call a collector ring 91(see Fig. 5) which is arranged on the armature shaft adjacent the commutator 94 and pro )erly insulated from said shaft in any usual or suitable manner. One segment of the commu tator, designated 92, is electrihally connected with said collector ring 9i by means of a wire or bolt 93 and through'the medium of the brush 42, said ring is in electrical connection. with the outside circuit. when the segment 92 is in contact with the brush 4], the current will not pass through any of the coils of armature 40, but when the segment 92, is diametrically opposite said brush 4], the current will have two equal paths through the armature 40, to the brush 4]. As the segment 92, approaches the brush 4 1, the resistance of the combined paths through the armature 40, decreases, and relatively increases as the segment 92, recedes from the brush 41. At such time or times as the segment '92, is opposite the brush 41, (that is, when it is at its furthermost point away from said brush), 'nearly the entire electromotive force of the battery 90, in the circuit just described, is expended in the armature 40, resulting in im arting rotation to the said armature 40. ut when, however, the segment 92 is in actual contact with the brush 41, nearly, if not quite, all the electromotive force of the battery 90 will be ex pended in the coil 28, resulting in increased 'niagnetization in the core 26. The regular recurrence alternately of the conditions above mentioned produce what may'propenergizes the coil 13, of the indication motor.

The current thus produced will cause the armature 12, of the indication motor N torotate and, as such rotation continues and increases, the balls 17 will move outwardly by centrifugal force, moving the connecting links 25 and bar 15, outwardly and upwardly, thereby lifting the latch 6, releasing the lever 1, and ermitting of a final movement thoroof, as s iown in Fig.3. It is only by a steady rotation of the armature that the centrifuge will be made to act to release the latch. Wherever I use the term rotation I mean suoh continued rotation as would be suflicient to cause a rotation of the centrifuge or other equivalent device to act u on the latch. This final movement of the ever cstablishes a new circuit, (see Fig. 3), in which current will flow from the battery 90, through wire 72, primary coil 28, wires 71 and. 65,
